retrieve_a_custom_deal_field_meta

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description adds 'Fetches data. Makes no changes.' which is consistent but does not provide additional behavioral context beyond the annotations. No contradiction.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded with 'READ-ONLY' and the HTTP method. It conveys the necessary information without extraneous text, making it easy to scan.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simple nature of the tool and rich annotations, the description is adequate. However, it does not mention the return format or data structure, which could be helpful since there is no output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the parameter 'id' is described in the schema as 'ID of the field to retrieve'. The description does not add any extra semantic meaning or usage details for the parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Retrieve a custom field' and 'Fetches data. Makes no changes.' It identifies the resource (custom deal field meta) and action (retrieve). However, it does not explicitly differentiate from similar sibling tools like retrieve_a_custom_field_meta, which could cause confusion.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies a read-only operation but provides no explicit guidance on when to use this tool versus alternatives (e.g., list_all_custom_fields_meta or retrieve_all_custom_deal_field_meta). It does not mention prerequisites or that an ID is required, which is already in the schema.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
